<h3>Background</h3> The aging process is a normal physiological phenomenon and has an impact on the body composition and physical fitness of the elderly. It is characterized by a progressive increase in total body fat mass, a decrease in muscle mass and changes in distribution in terms of an increase in abdominal fat tissue. These changes in the elderly have a great impact on health, functional capacity, and quality of life. The variability of body composition components contributes to the origin and progression of pathology and disability. Today osteodensitometric examination is considered one of the most versatile imaging techniques for assessing osteoporosis, sarcopenia, and obesity, and is currently the only technique capable of identifying all of these conditions at the same time. Osteoporosis is characterized by low bone mass and microarchitectural bone loss, leading to an increased risk of fracture caused by a minor trauma. <h3>Objectives</h3> To determine the presence of normal values of T score, osteopenia and osteoporosis, to determine the distribution of BMI and values of lean muscle mass, adipose tissue and visceral adipose tissue of the examined population. <h3>Methods</h3> In this retrospective study conducted from March to April 2019 at the University Clinical Center of Vojvodina, 699 respondents of both sexes over 65 participated. Exclusion criteria were established osteoporosis and treatment. The research consisted of collecting general information of the respondents (gender, age, smoking status, level of education, marital status). Body composition (BMD, FM, VAT, LM) was measured by osteodensitometric examination. Also, all subjects body weight, and height were measured and their body mass index (BMI) was determined. <h3>Results</h3> The average age of respondents was 71.92 ± 5.14, most respondents 50.6% have secondary education, 52.2% are married, 9.5% are smokers. The classification of the total T score shows a normal finding in 26.8%, with osteopenia 58.4% and with osteoporosis 14.8% of subjects. According to (BMI) with a normal finding is 16.5%, overweight is 38.5% and obese 45% of respondents. The average BMI of men is 28.79 ± 4.01, and for women the average BMI is 29.92 ± 4.91. The average value of VAT is 1,537 ± 0,820, FM 31,105 ± 9,152 and LM 43,735 ± 8,279. Men have higher average VAT values (2.06 ± 0.90) compared to women (1.32 ± 0.67). The average FM is higher in women (32.49 ± 8.88) than in men (27.60 ± 8.89). The average LM is higher in men (53.38 ± 7.05) than in women (39.92 ± 4.97). Subjects with normal findings were 61.5% obese, with osteopenia 40.2%, and with osteoporosis 28% obese. The measured value of LM in persons with normal findings is 47,921 ± 8,738, with osteopenia 42,342 ± 7,378, with osteoporosis 40,443 ± 6,949. The measured value of FM in persons with normal findings is 34.37 ± 9.51, with osteopenia 30.20 ± 8.75, and with osteoporosis 27.60 ± 7.14. The measured value of VAT in persons with normal findings is 34.37 ± 9.51, with osteopenia 34.37 ± 9.51, with osteoporosis 27.60 ± 7.14. <h3>Conclusion</h3> Higher values of BMI, LM, FM, and VAT have a positive effect on the hip and spine T score, and a protective role against osteoporosis. <h3>References</h3> [1]Salvio G, Petrelli M, Paolini S, Baldini V, Sbaffi C, Basili S, Giordano A, Balercia G, Cinti S.
